io mm; (ci. 5-356) The invention relai-.es to mattress' tuning. The

l objects of thefinvention are: to provide a tufting device which is simple in construction, will elciently hold the filling of the mattress, and can be quickly applied to the mattress; toprorvide a Amattress with improved tufting devices whereby the filling will be ventilated; and to provide an improved method of tuftlng.

Other objects of the invention and the various advantages and characteristics of the present mattress tufting will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and 'are more particularly defined by claims atthe conclusion hereof.

In the drawing which accompanies and forms a part of the present disclosure or specification and in which like numbers of reference denote corresponding parts throughout the several views: Fig. 1 is a section of a mattress having tufting devices embodying the present invention. Fig. 2 is a perspective of one of the studs of a device. Fig. 2 is a detail showing the tie of a device in the position assumed by the loops at its ends when they are attached to studs. Fig. 3 is a section of a modified form of the stud. Fig. 4 is a similar view illustrating another form of stud.

In tufting mattresses, it is customary to compress the mattress, to pass a tufting tie through the mattress tick'and filling by means of a needle and to attach a button to the end of the tie which has passed through the mattress. other button is usually applied to the tie before the latter is passed through the mattress. When the pressure of the apparatus used is released, the springs in the mattress will take up the slack in the tie and draw it taut to hold the buttons in engagement with the mattress tick.

In the preferred form of the invention, the

. tuftingdevices comprise a tie and a pair of studs. Each tie consists of a strip of cord or twine 6 of the desired length which is formed into a closed loop by knotting its ends together as at 7, so that there will be a looped portion 6El at either end of the tie for connection to a stud. Each stud comprises a tubular stem 8, and an out-turned curved flange 9 of sufficient width to bear against the outside of the mattress tick 10 around the hole made by the needle in passing the tie through the mattress. The inner end of each button is tapered, as at 8', to facilitate the entry of the tubular stem 8 through the mattress tick and into the nlling 10, through the The.

hole made by the needle. An approximately radial slot .'11 is cut through the flange 9 of each stud, and the stem 8 adjacent the flange is formed with notch 12 which communicates with the slot ll, so the tie can pass from the inside to the outsidev of the stem or vice versa.

In the manufacture of a mattress in accord` ance with the invention, the loop 6a at one end of the tie is threaded through the inner end of the tubular stem 8 of a stud, slipped through 65 the slot 11 in the flange 9 of the stud, then passed over the flange 9 and around the stem under the ange. The tie is then drawn to tighten the loop around the tubular stem in the annular corner between the stem 8 and flangei 9. 70 This will attach one end of the tie to a stud. The other looped end of the tie is then threaded into a suitable needle which is then forced completely through the mattress to carry the second loop of the tie to the opposite. face of the mattress. This second loop isthen threaded through the inner end of the tubular stem 8 of another stud, slipped through slot 11 in flange 9 and into notch 12, and looped over the 4flange and around the stem. This attaches the second stud tothe tie so that when the pressure on the mat-J tress is released, the springs 13 will expand the mattress until the tie is taut. The tapered portions V8 of the stems of the studs will pass through the holes in the tick made by the needle. The loops of the twine will underlie the flanges 9 snugly and be held around the stems 8 between the mattress-tick and the flanges, so the studs will hold the different portions of the mattress against displacement.

The innenends of the stems 8 of the studs are open for the passage of the tie therethrough, and the openings are of greater area than is necessary for the twine forming the tie, to provide an air passage to ventilate the material in the mattress. The studs, to which the ties are connected, thus serve to ventilate the mattress. The construction of these studs makes it possible to use a pre-formed loop, as a tie, and to attach the tie to the studs without any knotting or tying 100 operations betwen the tie and the studs, thus materially expediting the work in applying the tufting devices tothe mattress.

In Fig. 3 the stud is shown as provided with an exteriorly formed annular groove 15 at the 105 corner between the flange 9a and stem 8* to form a seat for the portion of the tie 6a which is lapped around the stem.

In Fig. 4 the invention is illustrated as applied to a stud without a closed loop in the tie. In 110 this construction, the notch l2b in the stem 8b and joining the radial slot in the ange 9b is not undercut so that one end of a cord 6b, after it has been drawn through the inner end of the stem 8b and lapped around the stem 8b under the flange 9b, can be slipped under that portion of the tie which has been laid in notch 12b, so the end will Je pinched by the overlying portion sufficiently to secure one end portion of the tie to the stud.

The invention exemplifies; a mattress tufting device, which is simple in construction, can be produced at a low cost, can be expeditiously attached to the mattress and will efficiently hold and ventilate the filling in the mattress; a mattress which is provided with tufting devices which vwill securely hold and ventilate the filling; and a method by which the mattress can be tufted at a low cost and expeditiously without requiring the tying of knots at the end of the tie which passes through the mattress.

The invention is not to be understood as re- I stricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what we claim as new and desire to secure by Letters Patent, is:
